Service Settings – Wireless Remote RG66
Service Settings are only accessible through the wireless remote
control.
Caution: Read and understand the function changes you wish to make
in advance. The remote will not read the parameters in the unit.
While many settings can be accessed, we find only the ones listed below may need
adjustment from default.
F1 Auto-Start – Turn OFF or turn back ON
F2 Heating Temperature Compensation – Adjust an offset based on thermal stratification
within the space.
F4 Indoor Fan Motor Speed Control after Set Point is Reached – Changes Heat fan speed
after set point is reached.
F7 Cooling Temperature Compensation – Adjust an offset based on thermal stratification
within the space.
1. Before using the service functions of the remote, turn
OFF the indoor unit with the remote.
2. Remove batteries from Wireless Controller, recycle power
to system and reinstall batteries.
3. Pointing the Wireless Controller at the Indoor unit’s
receiver, simultaneously press MODE and
TIMER ON for 5 seconds. When the display reads “F1”
you are in SERVICE FUNCTION mode.
4. Use TEMP + or − to find and display the parameter you
want to change.
5. When the parameter you want to change appears, press
MODE (parameters displayed after pressing MODE are
default values only, NOT the values stored in the unit. The
values are stored in the unit, not the controller. Pressing
MODE only displays the default value for that setting.).
6. To change the parameter use the TEMP + or − until the
value you want appears.
7. Press FAN to confirm the new setting value and transmit
it to the Indoor Unit.
8. Repeat steps 3 thru 6 for any other parameter you are
changing.
9. When finished, remove batteries from the remote and
press any button to clear the screen and then replace the
batteries and operate the system normally.
